Technical Details



SUHDLOG.DAT is created to the root directory of drive C: during the setup of Windows. It contains backup copies of the original boot sectors of the machine and the system files. This file is not used by Windows unless you uninstall it - in which case the boot sectors and system files are restored.If your machine was already infected by a boot virus before installing Windows, the infected boot sectors will be copied to SUHDLOG.DAT. After this, F-Secure anti-virus products will find a dropper infection from this file. This is pretty harmless, and the best way to correct this problem is to make an extra copy of the SUHDLOG.DAT to a floppy disk which is stored in a safe place (an expert could fix the file manually if you need it for uninstall purposes) and just delete the SUHDLOG.DAT file from your hard drive.On a related note, F-Secure Anti-Virus had a false alarm of the Lamerman virus in this file on June 15th, 2001.
